1. A method comprising:

  • receiving a depth map for a multi-view frame, the multi-view frame comprises a multi-view coding block and the multi-view coding block comprises a 2D coding block;

    computing a depth quality sensitivity measure for the multi-view coding block in the multi-view frame based in part on the received depth map;

    computing a depth-based perceptual quantization scale for the multi-view coding block, wherein the depth-based perceptual quantization scale is based on the depth quality sensitive measure and a base quantization scale for the multi-view frame; and

    encoding the 2D coding block using the depth-based perceptual quantization scale.
